IMPROVEMENT IN slPl-loNs.

Specification forming part of Letters Patent No. 157,474, dated December 8, 1874; application filed January 15, 1874.

To all whom it may concern.:

Be it known that I, vEDWARD T. JENKINS, of Williamsburg, in the county of Kings and State of New York, have invented certain Improvements in Siphons, of which the following is a full, clear, and exact description, reference being had to the accompanying drawing and to the letters of reference marked thereon, making part of this specification, in which is represented a vertical sectional view of my improved Siphon.

The object of my present invention is to provide a Simple, safe, and practical means for decantin g liquids, especially acids and other like dangerous and costly liquids, and which permits of their being transferred or drawn off from a carboy or other receptacle into a suitable vessel without danger of spilling, and Without in any manner disturbing the supply-vessel.

The nature of my invention consists in connecting the legs, or the discharging and receiving limbs of an ordinary siphon, with a cone-shaped shell-collar, into the inner chamber of which leads an air-tube, and which latter is provided with a check-valve and embouchure, the whole being so arranged that the mouth of the operator is freed from all danger of being brought in contact with either the vessel or its contents, and the valve so operating as to automatically drop and retain whatever pressure the operator may have blown into the vessel, and which is exceedingly useful in starting the ow of the liquid,

especially in case the operator is not able tostart the liquid running by a single operation.

rThe construction and operation of my invention are as follows:

A is a cone-shaped shell-collar, made of metal or some other rigid substance, and threaded at a for the purpose of screwing it tight into wooden vessels. Over the threaded surface c I place, when necessary, the annular cap A', which is made of rubber or some other yielding material, so that it can be pressed tightly into the oriice or neck of the ordinary carboys, which are generally constructed of unyielding material. B and B are two arms, and serve in adjusting the collar A into the vessel in connection with which the Siphon is used. The arm B is hollow, and terminates in a valve-chamber, in

which rests and operates the stop-valve b. C is a mouth-piece or embouchure, through which the operator applies the necessary pressure to start the Siphon. D is the receiving leg or limb of the siphon, and D is the discharge leg or limb of the siphon, and may be formed out ot' a single tube of rubber or any other suitable material 5 or they may be formed, if desired, out of independent tubes, and may be of any desired shape, length, and capacity. These legs are connected with the cone- Shaped collar A by means of a stuffing-box, E, and which provides a perfectly-'tight joint.

From the foregoing description the operation of my improved Siphon will readily be understood. `Into the opening of the containing-vessel, or the vessel from which it is desired to decant the liquid, you insert the coneshaped collar A. lf the vessel is of wood you form a tight joint by screwing the thread a into the same, and if of an unyielding materia-l you use the rubber cap A. The receiving leg or limb D being in the vessel, its opening or orifice d being submerged in the liquid, and the opening d' being in contact with the vessel which you desire to fill, the operator has simply to place his mouth on the embouchure C and blow into the vessel through the hollow arm B until the iiuid is started, when the valve b drops and retains the pressure in the vessel, and thus insures the uninterrupted iiow of the liquid. This valve b is also useful and most important in case the operator cannot with a single breath start the liquid, as it drops and retains the pressure blown in while he regains his breath for a second operation.

What I claim as new, and desire to secure by Letters Patent of the United States, is

The cone-shaped collar A, legs D D', stuifing-boX E, hollow arm or tube B, having a valve-chamber, the valve b, and embouchure C, the whole being combined andarranged to operate substantially as described.

In testimony whereof I have hereunto signed my name to this speciiication in the presence of two subscribing witnesses.
